To @ZZ whom it may concer-n.-

Be it known; that .we,WARRn`N C. vEvA-Ns,

of Exeter, countyl'of Rockingham, State 'of New Hampshire, and HENRY D.ALLARD, of

5 Bradford, and JOHN B. ,KENISOBL of Lynn,

county of Essex, StateofMassachusetts, have in vented an ImprovementinSole-Edge-Blackf ing Machines, of whichthe following description, inconnectiouwiththe accompanying :o drawings, is a specification, likeletters andl numerals on the drawingsrepresenting like parts.

This invention 'hasfor its objectA the production of a novel,convenient, and highly- I5 efficient apparatusf'or applying blacking orother coloring-matter tothe edges of boot and shoe soles and heelsrapidly and accurately with an even coating of any desired density.

Means are provided to absolutely prevent 2o the coloring-matter, whichterm as herein used includesv blacking, from touchingithe. upper or thetop of the sole when desired, as" in fair-stitch Work, thecoloring-matter being applied without spattering by a rotary z5transferrer, against which the Work is held,` and the arrangement Vofthe mechanism is' such that the coloring-matter can ybe appliedto thesole edge only or to the edge and top,

as may be desired. 30

tor moves the work the color isapplied to that portion thereof .Whichhasbeen j ust beg5 fore smoothed, so that subsequent rubbing down isobvia-ted.

In the course of our experiments to improve apparatus of this class sothat the coloring-matter shall be applied in a smooth;

We have also made provision for scouring, "ond bearing a. or smoothingthe sole edge jnstbefore the color is applied thereto, so that as theoperafast on the shaft.

plyingcoloring-matter to boots and shoes as willbe described. 'Fig. 2 isayerticalsectionalview thereofon the linearer, Fig..l, looking tothe'.right. Fig. 3 is a rearfelevationof .the'apparatus Figa is a like,view, 'enlargedtaken through the main or driving `shaft andv a portionof-o'ue of kthe reservoirs forthe coloring-matter, showing also insection the guard orshieldand theintermediate controlling devicesbetween the reservoir and the color-transferrer. Figi 5 is an inner.side view of the clutch mechanism on the drivingshaft shown at theright,: Fig. Y1'. Fig. 6 is a vertical sectional View taken through thelongitudinal axis of the main or driving shaft, showing a portion of theclutch mechanism.

Fig. Sis a detail elevation showing thedevice for scouring or smoothing the edge of the sole and in connectionywith the colorapplying mechanism. j

Referring to Fig. l, the mainframe A, of suitable shape to support theworking parts of the apparatus, is preferably mounted on a shelfor-stand A', said frame having an upright A2, which provides a bearingjafor the e main driving-shaft B, the latterhaving a sec- A gear `C isfasten the shaft B adjacent the inner end 4'of the bearing a', and atthe other end of the said bearing'abuts lthesleeve-like hub b of aclutch member B',

bly mounted on the hub b and retained in 4place by a collarbx, fast onthe main shaft, said clutch member having its inner face concaved .ordished, as clearly shown in Fig. 6. A dog b2 (see dotted lines', Fig. 5)is secured to the outer end of a stud b', mounted to rock in the clutchmember B', saidY ldog at times engaging a stop b3, secured on the inneror A concave face of theclntch member Bavhile on the inner side of themember B' a trigger b4 is rigidly secured to the stud h'. A spring Theother or loose clutchl member is shown asa cone-pulley B2, rotata- IOCAroek-shaft b5, Figs. l, 2, 3, and 5, is mounted on the main frame andin the standard A2, f

a set-screw 5 adj ustably securing on the rockshaft an arm 1), on whichis mounted a headed spring-controlled stud 137, normally held in thepath of movement of the lip of the trigger by a suitable spring S,(partially shown in Fig. 5,) the tripping of the trigger disengaging thedog and stop b3, and so disconnecting the clutch members when the lip ofthe trigger engages the headed stud 117, the rotation of the clutchbeing in the direction of the arrow 75, Fig. 5. As shown in said Fig. 5,the trigger 114 is supposed to have just engaged the stud 1)?, andslight further rotation of the'clutch will tip the trigger to move thedog 122 out of engagement with the stop 133. By making the triggerdouble, as shown, its inner end engages the hub of the clutch member Bwhen tipped inward to thereby prevent undue movement of the trigger.

An actuating-arm bs, (see Figs.y l and 2,) fast on the rock-shaft 1), isadapted to be moved by the operator to rock the shaft b5 in thedirection of the arrow'O, Fig. 5, against the spring S, to therebyWithdraw the clutchcontroller stud D7 from engagement with the trigger,so that the clutch will be thrown into operation and the main shaftrotated. The arm 1) has laterally projecting from its inner face a lug1), adapted to be engaged by a shoulder 1910 on a lever blz, pivoted onthe frame at 1113, so that when the actuating-arm D8 is depressed tosupport the apparatus the shoulder 1110 will engage the lug 1), andthereby maintain the clutch in operative position until the operator, bylifting the lever 1212, releases the lug, permitting thereby therockshaft b5 to return to normal position and through the clutch-controlling stud 1F engage the trigger and, as described, effect thedisengagement of the two clutch members.

The main shaft has secured thereon (see Figs. l, 3, and 4) separatedcollars 7 S, to receive between them an arm c, mounted to rock on thepreferably-enlarged portion B3 of the main shaft, said arm at its rearend having a bearing c', through which is extended a shaft c2, on theouter end of which is secured a suitable scouring or smoothing roll cx,having a roughened periphery and, as shown best in Fig. 3, slightlyconical in shape. At its inner end the shaft c2 has fast thereon asuitable pulley c",to which rotation may be transmitted by a belt-(notshown) from any suitable source of power to rotate the scouring-roll 0Xin the direction of the arrow G5, Fig. 8. A bracket cl on the standardA2 is threaded to receive an exteriorly-threaded sleeve c5, providedwith a suitable check-nut c6, the upper end of the sleeve being located`below the rear end of the arm c, as clearly shown in Fig. S. A spring Sis'attached at one end to saidvarm and at its other end to a rod c7,extended loosely through the lower end of the sleeve c5 and threaded toreceive thereon an ad justin g-nut cs, by which the tension of thespring may be regulated. lt will be seen that the scouringroll is thussupported to rock bodily by and at the rear of the main shaft, thespring holding it in a yielding manner against the sleeve,

the latter being adjusted in its bracket to suit different shapes ofshoes and to cooperate properly with the color-transferrer, to behereinafter described.

The spring S can be adjusted independent of the sleeve,and theadjustment of the sleeve will also,if desired,a'ffect tension of thespring.

The color-transferrer is herein shown as an annulus T, having acontinuous non-metallic and slightly-yielding peri phery,and up to thepresent time we have obtained the best results with a rubber transferreror one having a rubber periphery, as the color will thereby be ap-Vplied to the Work smoothly and evenly without streaking or spattering.-

)Ve prefer to give a slightly-conical form in yan outward direction tothe periphery of the transferrer,to thereby secure the more perfect fdistribution of the color over the work, the edge of the sole being heldby the operator against the transferrer as it is rotated, the latterbeing applied, as shown in Fig. Ll, to the yenlarged portion B3 ofthemain shaft and abutting against the collarrS.

The edge of the sole from the shank portion forwardly around the toe ispreferably scoured, while it is unnecessary to scour the shank portion,and we have shown our apparatusfas provided with two transferrers TT',the former only operatingin conjunction with a scouring-roll, so thatthe shoe will be first applied to the transferrer T, the color beingapplied as the operator draws the shoe toward him, the rotation of thescouring-roll being such that any dust from the l.sole is thrown awayfrom the. transferrer, and afterward the sides and fore part of the soleedge IOO IOS

are colored, and the shoe is then applied to the transferrer T,whichcolors the shank. This arrangement, however, is largely a matter ofconvenience to the operator, as one machine can thus do the work of twoseparate ones, while it will also be obvious that the scouring-roll canbe thrown out of operation at times, if it is desired to use one and thesame color-transferrer for both the shank and fore part of the sole. Thetransferrer T is mounted on a shaft B4, held in suitable bearings on theframe and having fast thereon a gear B5, which meshes with anintermediate gear B in mesh with gear C, fast on the main shaft, so thatthe two transferrers are rotated in the same direction. Each transferrerhas its own reservoir for the coloring material, which term includesblacking, and as the reservoirs and their operative parts arecounterparts one of the other only one will be described in detail, thereference-letters D 61d of the one corresponding,respectively,to theletters F. e e' of the other.

' The main frame A has on its front and rear IIO IZO

work of the apparatus.

'scenes fe sides lugs A16 A17. to receive the shanks of yokes al a toembrace the upper ends of the reservoirs D E, respectively.

Thelreservoir D (see Fig. 4:) is open at its lower end andreceivestherein an upturned annular flange d, formed on thebottom plate D',which bottom plate is provid ed with a lateral. extension D2, providedwith a boss d','

through which is extended a screw-bolt d2, the latter fitting into ahorizontal notch dx. in a part of the standard Awhile a thumb-nut d3 atthe opposite end of the screw-bolt acts to clamp the extension D2 firmlyto the frame- The reservoir is secured to its bottom plate in anysuitable manner, either by Soldering or by a ground joint to hold in thecolor without leakage. The bottom is slotted 'at d4 above thetransferrer T, said slot serving as an outlet furthe contents of thereservoir, while a valve, shown as a rod d5, is adapted to movelongitudinally in the reservoir-bottom, the inner end of the rod passingthrough an ear d on the under side of the `extension D2, longitudinalmovement of the valve opening more or less the outlet, a springs',connected at one end to the ear d and at its other end to a pin d'7 onthe rod, normally retracting the latter to open the outlet dl. The piudis adapted to be engaged when desired by a gravity-latch cls, pivotedon the exterior of the extension at Z9 (see Fig. I) to hold the valve insuch position as to close the outlet, as would be the case when themachine is not in use.

The coloring-matter does netpass directly from the outlet d4 onto thetransferrer, but onto a small distributing roll f, pivot-ally mounted inrocking supports f', fulcrumed at j2 in the downturned iange of a blockfx, attached to the under side of the bottom plate D', the outer ends ofthe supports f' being n icked to receive the annular heads of suitableadjusting-screws f3, :threaded into the block fx, so that rotation ofthe said screws will raise or lower the distributing-roll f to pressmore or less tightly upon the transferrer.

It is found in'practicethat the interposition of the distributer betweenthe reservoir-outlet and the transferrer greatly assists in the smoothand even distribution of the ink upon' the transferrer, and alsoprevents spattering.

A piston-rod or plunger d10, vertically movable through the upper closedend DX. of the reservoir, has a head or piston (112 secured thereto toenter loosely the reservoir and at its inner stroke tol fit' quitesnugly within the.

flange d, while when the'plunger is lifted its head C112 will be raisedabove the l(lange, so that a portion of the material in the reservoircan pass beneath the head vto be positively expelled th rough the outletd4 when the plunger is next depressed.

A slide-rod mx, vertioallymovable in bearl ings 22 33 of the 'mainframe, has l.attached thereto arms m m', which engage the two Vplungersd10 and elo, between collars 3 4 thereon, respectively, to effect thereci procation of the plungers, the slide-rod being depressed by aspring S5 and elevated by engagement with one arm m2 of a bell-cranklever pivoted on the main frame at m3, the other arm m4 of said leverbeing located in the path of and to be engaged by a cam-lng BS on theinner side of the gear B5, as clearly shown in Fig. l, whereby theplungers will be elevated and depressed ouce for every completerevolution of the transferrers.

We have provided means for automatically closingV the reservoir-outletswhen the machine is stopped, so that the coloring-matter will not atsuch time flow, and for this purpose an inclined shaft 7L is mounted torock in bearings in brackets 30 and 31 on the main frame and standardA2, respectively, said shaft being provided at its lowery end with a toeh'. in the path of and to be engaged bya tappet h2, fast on thehorizontal controllingshaft h5, thev tappet engaging, as best shown inFig. 2, an adjusting-screw h3 in the toe. At its upper end therock-shafthas adjustably seeuredthereto an arm hextended forwardly tobear against the valve-rod e5, as shown in 3.when the parts are in thepositions shown in Figs. l, 2, and 3.

the inner end of the. toe 71,' and the collar hx, fast on the shaft,said sleeve being provided with a forward ly-extended arm h2 adapted tobear against the exposed end oi" the valverod` d5 when the machine isnot in use. The sleeve h5 has a toe h7at its lower end, provided with anadjustable stud 718, to be engaged by" a tappet h, fast on thecontroller-shaft b5. Now when the machine is at rest the two tappets onthe'controller roel-shaftfb5 will act on the cooperating toes of therock-shaft it and sleeve hi to turnV the arms h4 and h6 to the left,Figfl, forcing the valve-reds to nearly close `the reservoir-exits, sothat the iiow ofvcoloring-matter will be greatly diminishedjt beingsufficient to partially shut off the flow when the operator removesonebooter shoe and is about to present another one to the colortransferrer.lf, as has been, described, .the coloring-matter is entirely shut off,as when the machine is leftfor the day or for any length of time, theoperator will grasp the extensions M0716 of the arms 71,4 h6,respectively, pushing them to the left until each valve-rod is caught byits gravity-detentds or e8.

Movement of the valve-rods to the right, Fig. 1,'is limited by threadedstuds d50 e5", mounted .in -the main frame and adapted to impingeagainst the varms h4 h6, respectively.

0f course a greater quantity of the coloring-matter must be deliveredwhen it is thick A sleeve h5 is loosely mounted on the shaft it, betweenIOO IIO

than when it is thin, and in the former case hereinbefore described, ashield is unnecessary; but .it is necessary to provide a guard toprotect the upper, and We provide such guard and at the same time effectthe application of the coloring-matter to the top of the sole.

The bottom of each reservoir is provided with a standard, one' beingshown in section at d20, Fig. 4, interiorly threaded at its lower 'endto receive a stop-screw dim, through which is extended avertically-movable,shank cl2?, the upper end of which is received in alongitudinal hole C223 of the standard, the upper end of the hole beingthreaded to receive an adjusting-screw d24. The inner end of said screwis shown as bearing on a ange di, which rests upon the top of a springs3, the lowerend of which is seated in the recessed upper end of theshank C122, and by adjusting the screw 24 the tension of the springisvaried. A thin guard-plate 0526 is secured to the lower end of thefoot CX22, adjacent the outer end-of the transferrer T, saidguard-plater 7iiowing from the guide onto the top of the sole,while theedge of the latter has color applied thereto bythe transferrer T.l

The coloring-matter is prevented from passing under the lower edge ofthe guard-plate and onto the shoe by the groove d2?, inwhich thecoloring-matter collects and drops onto the wire guide CPS, which thusserves not only to apply the coloring-matter to the top of the sole whendesired, but it also furnishes a guide for the operator in manipulatingthe shoe, such manipulation being assisted by a bottom gage, shown as atruck n on a stud n', extended out from the standard A2.

The shank d is provided with a pin 45, Fig. 4, which rests on the top ofthe stopscrew C321, and by adjusting the latter the eX- treme lowerposition of the guard-plate and guide is provided for.

To prevent any accidental loosening of the stop-screw, a clamping-screw46 is extended through the body of the standard d20 to bear against thestop-screw d21 and prevent its rotation.

The guard-plate is held in parallelism with the outer end of thetransferrer T by means of depending ears cl2, bearing on the outer faceof the guard-plate CX26.

The guard is used for all plain work and about the Shanks of boot andshoe soles; but with fair-stitch work it is necessary to protect notonly the upper, but also the stitching at the top of the sole, and indoing such work the transferrer is moved slightly away from and out ofcontact with the guard-plate, so that vno coloring-matter will passthereto from the said transferrer, and in Figs. 1 and 2 thecolor-transferrer T1 is shown as moved slightly to the right for thispurpose.

The movement of the transferrer is readily effected by adjustment of thecollar 90 on the shaft B4. The operator holds the boot or shoe in hishands, with the bottom of the sole against the bottom gage a and withthe edge of the guide C128 in the crease between the sole and the upper,and the edge of the sole is pressed up against the edge of the rotatingtransferrer, this upward movement of the shoe and guide being permittedby the yielding support for the guide, and the transferrer applies theblackin g or coloring-matter evenly and rapidly to the sole edge as itis turned to present new portions thereto, the guard-plate protectingthe upper efectually. rlhe movement of the boot or shoe is toward theoperator, so that when the scouring-roll is used the sole edge isscoured just before it is moved into contact with thecolor-tra-nsi'errer. The operation will be precisely the same infairstitch work, with the exception that, as has been described, theguard and color-transferrer would be slightly separated to prevent thepassage of color from one to the other.

With some kinds of coloring-matter or stain it is desirable to maintainit heated when the apparatus is in use, and for that purpose we haveprovided burners P and P', (best shown in Fig. 3,) located beneath thereservoirs D and E, respectively, on branch pipes p p',

` leading `f rom a common `pipepx, which may be connected with anysuitable gas-supply,

In the claims we have herein used the term coloring apparatusgenerically,l said term including blacking or other coloring-matter lorstain which is to be applied to the edge or upper portion of a boot orshoe sole.

In this application we do not claim in a soleedge-blacking apparatus arotatable brush against which the sole edge is held with an adjacentreservoir provided with a dischargeopening to deliver its contentsdirectly upon the brush, means to positively force the contents of thereservoir through the opening, and an automatioally-controlled valve forsuch opening, as they form the subject-mattei' of a claim in anotherapplication, Serial No. 681,502, renewed May 23, 1898, by two of theinventors herein named, the color-applying device in the presentinvention consisting of a rotatable member having a continuous yieldingperiphery as opposed to a brush the periphery of which is formed of amultitude of independent bristles.
